FIELD OF THE INVENTION

The invention relates to a control arrangement for controlling thetransfer of agricultural crop from a harvesting machine to a transportvehicle.

BACKGROUND ART

When harvesting agricultural crop on a field it is established practicethat a harvesting machine loads a transport vehicle, which movesalongside the harvesting machine, with harvested crop. A loadingcontainer of the transport vehicle which is, for example, a tractor witha trailer or a truck, when travelling is loaded with the harvested cropby means of a discharging device of the harvesting machine, for examplein a forage harvester via a discharge shaft and in a combine harvestervia an ejection duct. The discharging device is generally fastenedrotatably to the harvesting machine about a vertical axis and ispivotable between a resting position in which it is orientedapproximately parallel to the longitudinal axis of the harvestingmachine and an operating position in which it extends transversely tothe direction of travel of the harvesting machine. Additionally, theheight of the end of the discharging device on the discharge side may bevaried, as may be the position of an ejection flap which defines theangle at which the harvested crop is discharged.

In discharging devices which may not be adjusted in their dischargeposition, as used conventionally in combine harvesters, the driver ofthe transport vehicle has to ensure that the loading container is filleduniformly and fully by gradually positioning different points of theloading container below the discharging device. This task is relativelydemanding and tiring as losses of harvested crop due to harvested cropfalling onto the field have to be avoided.

With adjustable discharging devices, as used conventionally in forageharvesters, in the simplest case the position of the discharging deviceis manually controlled by the driver of the harvesting machine, forwhich input devices are available to the driver in the cab, whichactivate actuators used for adjusting the discharging device. In thisconnection, the driver of the harvesting machine has to ensure that theentire loading container of the transport vehicle is sufficientlyfilled, which is carried out by successively aligning the dischargingdevice with different points on the loading container. Should thetransport vehicle deviate from its desired position forward or backwardor to the side, the position of the discharging device has to bemanually readjusted. In this connection, it may be regarded as adrawback that the control of the position of the discharging devicetakes up a considerable portion of the attention of the driver whichresults in tiring work for the driver of the harvesting machine.

Published German patent application, DE 44 03 893 A1 discloses a forageharvester comprising a discharging device, at the ends thereof on thedischarge side a distance meter being attached, which detects the levelof the harvested crop in the loading container. As soon as the harvestedcrop has reached a predetermined level, the discharging device isadjusted until the entire loading container is filled. In this case, theprocess is automated which substantially relieves the burden on thedriver of the harvesting machine but which requires a costly distancemeter.

In European patent application EP 1 219 153 A, it has been proposed tomove the loading container automatically or manually relative to theharvesting machine into a position in which it may be filled. In fixeddischarging devices (combine harvesters), information about the positionof the discharging device is transmitted by means of a remote datatransmission device to the transport vehicle and the position of thetransport vehicle adapted, whilst movable discharging devices (forageharvesters), based on data regarding the position of the loadingcontainer and its own position, are automatically moved into a positionin which they fill the loading container. If the driver identifies thata region of the loading container has been sufficiently loaded withharvested crop, and now a different region has to be filled, theposition of the discharging device is manually altered by the driver ofthe harvesting machine. If the range of movement of the dischargingdevice is no longer sufficient in order to reach insufficiently filledregions of the loading container, the relative position of the transportvehicle to the harvesting machine is automatically altered, which mayalso take place in the opposing direction to the discharging device.Accordingly, the discharging device is automatically alignedcontinuously with a specific position on the loading container. Thedriver of the harvesting machine is, however, not relieved of the taskof monitoring the cone of bulk material of the harvested crop collectingon the loading container and, if required, moving the discharging deviceinto a new position.

European patent application EP 1 645 178 A proposes to guide thedischarging device of a forage harvester along a defined geometry, whichmay be a straight line or curved path extending in the centrallongitudinal direction of the loading container. Also in this case, theposition of the discharging device is changed by an input from theoperator. Relative to the disclosure of EP 1 219 153 A the operator ismerely relieved of the choice of a new position of the dischargingdevice.

In the publications “Assistenzsystem zur Überladung landwirtschaftlicherGüter” (“Assistance System for transferring Agricultural Crops”) by G.Wallmann and H. H. Harms, Landtechnik 2002, pages 352 and 353, and“Häckselgut automatisch überladen” (“Automatic Transfer of ChoppedMaterial”) by A. Bohrnsen, Profi November 2006, pages 84 to 86, it isproposed to implement a loading strategy by means of the dischargingdevice which effects a uniform and complete loading of the transporttrailer by an alignment with different target areas in a clocked manner.To this end, the discharging device and its ejection flap may be guidedin a zig-zag pattern, or alternatively only the ejection flap iscontinuously pivoted to and fro, whilst the transport vehicle isgradually moved further forward or backward by its driver. In this case,monitoring of the loading container is no longer required by the driver,as the control of the discharging device is carried out fullyautomatically. However, it is not taken into account by the set loadingstrategy that the most appropriate filling method in each case may alsodepend on the type of transport vehicle. Thus trucks with driven rearaxles initially have to be loaded above the rear axle, whilst incontrast semitrailers have to be initially loaded in the front region ofthe trailer in order to ensure the traction capacity. In the prior art,the type of terrain is also not considered which may also have an effecton the best loading strategy in each case where there are lateralinclinations or inclinations present in the direction of travel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S)

In accordance with one embodiment, the control arrangement provides forcontrol of the transfer of agricultural crop from a harvesting machineto a transport vehicle comprising a loading container, where the controlarrangement may be flexibly adapted to the type of transport vehicleand/or the respective operating conditions.

A control arrangement serves for controlling the transfer ofagricultural crop from a discharging device of a self-propelled orattached or pulled harvesting machine to the loading container of atransport vehicle. During the harvesting operation, the controlarrangement influences the position of the discharge end of thedischarging device and/or the direction of ejection of the dischargingdevice and/or the position of the transport vehicle relative to theharvesting machine. The latter takes place by said control devicetransmitting steering and/or speed signals to a steering and/or speedsetting device of the transport vehicle or a suitable display on thetransport vehicle or the harvesting machine, using which the driver ofthe transport vehicle steers said transport vehicle and/or controls thespeed thereof. Thus the harvested crop is automatically deposited by thecontrol arrangement according to a predetermined loading strategy, whichis stored in a storage device, successively at different points of theloading container. The loading strategy is able to be changed and/or achoice is able to be made between different loading strategies.

In this manner, the loading strategy may be adapted in an improved oroptimized manner to the respective circumstances of the filling process.A detection of the level of the harvested crop on the loading containeris not necessary, although it might be possible in principle.

The loading strategy may be selected depending on the type of transportvehicle, in order to load, for example, the trailer of a semitrailerinitially in the front region, where the driven axles are located,whilst a truck with a driven rear axle is loaded initially in the regionabove the rear axle. In a similar manner, in a tractive machine with twotrailers, initially the front trailer is loaded.

Moreover, the loading strategy may take into account the maximum load ofthe transport vehicle, in order to prevent overload. The maximum load(and thus the transfer time associated with the individual points of theloading container and the quantity of harvested crop deposited thereonafter completing the loading of the loading container) may depend onfactors, in particular dimensions of the transport vehicle and/orstatutory requirements. Also, the potential weight distribution on thetransport vehicle may be taken into account, so that if required moreharvested crop may be deposited in the vicinity of the axles than inother regions of the loading container. Moreover, the loading strategymay depend on the ground conditions of the terrain which is driven on,for example on the traction capacity and/or load-bearing capacity of theground. As a result, the wheels of the transport vehicle may beprevented from spinning or sinking into the ground when under too greata load. The ground conditions may be stored in a suitable electroniccard accessible to the control device and may be retrieved by means of aposition determining device (for example a GPS antenna).

The information used by the control device regarding the properties ofthe transport vehicle (for example the type of transport vehicle such asa semitrailer or truck or tractive machine and the number of trailerspulled, the position of the driven axle or axles, the dimensions of theloading container, the maximum load, the potential weight distribution,the traction capacity on different surfaces) may in a simple embodimentof the invention be supplied to the control device by the operator bymeans of an input device. The corresponding data are typed in or set viainput keys or selected from menus. In a further embodiment, theinformation is transmitted by suitable storage means and transmittingdevices from the transport vehicle to the harvesting machine. To thisend, data may be transmitted by radio or optically, or the transportvehicle has a barcode, a transponder chip or an RFID chip, which may beread by the control arrangement. Based on this information, the controlarrangement alters or selects the most suitable loading strategy in eachcase or modifies it.

The loading strategy may further depend on the inclination of theterrain in the direction of travel of the harvesting machine and/or inthe lateral direction. The inclination is detected by means of aninclination sensor located on-board the harvesting machine and/or readfrom a card using the respective position and direction of travel of theharvesting machine detected by a position determining device. Theloading strategy will ensure that the discharging device fills up theregions of the loading container which are respectively located uphillto a greater extent than its regions located downhill, in order toprevent harvested crop from falling to the ground. If the harvestingprocess takes place according to a path plan which is planned inadvance, the inclination to be expected during the path to be covered isalready known, so that the loading strategy may be adapted in advance tothe anticipated inclination.

A combination of two agricultural machines shown in FIG. 1 comprises aharvesting machine 10 in the manner of a self-propelled forage harvesterand a transport vehicle 12 in the manner of a self-propelled tractorwhich, by means of a towbar 14, pulls a trailer 16 which comprises aloading container 18.

The harvesting machine 10 is built on a frame 20 which is carried by thefront driven wheels 22 and steerable rear wheels 24. The harvestingmachine 10 is operated from a driver's cab 26 from which a harvestingattachment 28 in the form of a maize threshing attachment is visible,which is fastened to an inlet channel 30 on the front face of the forageharvester 10. By means of the harvesting attachment 28, harvested croppicked up from a field 34 is conveyed via an inlet conveyor, arranged inthe inlet channel 30 and comprising pre-compacting rollers of a choppingdrum 36, which chops the crop into small pieces and supplies it to ablower 38. Between the chopping drum 36 and the blower 38 extends a finecrushing device 42 comprising two grain processing rollers. Theaforementioned driveable units of the harvesting machine 10 and of theharvesting attachment 28 are driven by means of an internal combustionengine 44. The crop discharged by the blower 38 leaves the harvestingmachine 10 in the direction of the loading container 18 driven alongsidevia a discharging device 40 in the form of an ejector pipe, which may berotated by means of a first, external force-actuated actuator 46 aboutan approximately vertical axis and which may be adjusted in inclinationby means of a second external force-actuated actuator 48, the directionof ejection being able to be altered by a flap 50, and the inclinationthereof being able to be adjusted by means of a third externalforce-actuated actuator 52.

The transport vehicle 12 and the trailer 16 are of conventional design.The transport vehicle 12 comprises front steerable wheels 64 and reardriven wheels 66, which are supported on a frame 68 which carries adriver's cab 70.

In FIG. 2, the harvesting machine 10 and the transport vehicle 12 areshown in plan view. It may be seen that the harvesting machine 10 movesalong the edge of the harvested crop 54, which represents a boundarybetween the harvested region 56 of the field 34 and the plant population60 of the field 34 which is still upright and full of maize plants 58,and which harvests the plants 58. The transport vehicle 12 drives on theharvested part 56 of the field parallel to the harvesting machine 10along a path on which the plants chopped by the harvesting machine 10pass through the discharging device 40 into the loading container 18.The transport vehicle 12, therefore, always has to drive parallelalongside the harvesting machine 10; in particular when driving into thefield, however, the transport vehicle 12 may also drive behind theharvesting machine 10 as no harvested part 56 of the field 34 is presenton which the transport vehicle 12 could drive without damaging theplants located there.

The harvesting machine 10 is steered by a driver sitting in the driver'scab 18 or by an automatically operating steering device known per se.The transport vehicle 12 is also provided with a steering devicedescribed in more detail hereinafter, in order to simplify and/orautomate travelling parallel with the harvesting machine 10. Theharvesting machine 10 could also be any other self-propelled harvestingmachine, such as a combine harvester or beet harvester.

The harvesting machine 10 is provided with a first position determiningdevice 72, which is located on the roof of the cab 26. Here a firstradio antenna 74 is also positioned. The transport vehicle 12 isprovided with a second position determining device 76, which is locatedon the roof of the cab 70. Here a second radio antenna 78 is alsopositioned.

Reference is now made to FIG. 3, in which the individual components ofthe position determining devices 72, 76, and the steering devices of thetransport vehicle 12 and of the harvesting machine 10 are shownschematically. The first position determining device 76 is locatedon-board the harvesting machine 10, said first position determiningdevice comprising an antenna 80 and an evaluation circuit 82 connectedto the antenna 80. The antenna 80 receives signals from satellites of aposition determining system, such as GPS, Galileo or Glonass which aresupplied to the evaluation circuit 82. Using the signals of thesatellites, the evaluation circuit 82 determines the current position ofthe antenna 80. The evaluation circuit 82 is further connected to acorrection data receiving antenna 84, which receives radio waves emittedfrom reference stations at known locations. Using the radio waves,correction data for improving the accuracy of the position determiningdevice 72 is produced by the evaluation circuit 82.

The evaluation circuit 82 transmits via a bus line 86 its positionaldata to a computing device 88. The computing device 88 is connected viaan interface 90 to a receiving and transmitting device 92, which in turnis connected to the radio antenna 74. The receiving and transmittingdevice 92 receives and generates radio waves which are received and/oremitted by the antenna 74.

Similarly, the second position determining device 76 is located on-boardthe transport vehicle 12, said second position determining devicecomprising an antenna 94 and an evaluation circuit 96 connected to theantenna 94. The antenna 94 receives signals from satellites of the sameposition determining system as the antenna 80, which are supplied to theevaluation circuit 96. Using the signals of the satellites, theevaluation circuit 96 determines the current position of the antenna 94.The evaluation circuit 96 is further connected to a correction datareceiving antenna 98, which receives radio waves emitted from referencestations at known locations. Using the radio waves, correction data isgenerated by the evaluation circuit 96 for improving the accuracy of theposition determining device 76.

The evaluation circuit 96 transmits via a bus line 100 its positionaldata to a computing device 102. The computing device 102 is connectedvia an interface 104 to a receiving and transmitting device 106, whichin turn is connected to the radio antenna 78. The receiving andtransmitting device 106 receives and generates radio waves which arereceived and/or emitted by the antenna 78. By means of the receiving andtransmitting devices 90, 106 and the radio antennae 74, 78 data may betransmitted from the computing device 88 to the computing device 102 andvice versa. The connection between the radio antennae 74, 78 may bedirect, for example provided in an authorized radio range such asCB-radio, amongst other things, or via one or more relay stations, forexample when the receiving and transmitting devices 90, 106 and theradio antennae 74, 78 operate according to the GSM standard or anotherappropriate standard for mobile telephones.

The computing device 102 is connected to a steering device 108, whichcontrols the steering angle of the front steerable wheels 64. Moreover,the computing device 102 transmits speed signals to a speed settingdevice 110 which, by varying the engine speed of the transport vehicle12 and/or the gear ratio, controls the speed of the transport vehicle12. Moreover, the computing device 102 is connected to a permanentmemory 120.

On-board the harvesting machine 10 the computing device 88 is connectedto a control unit 112, which together with the actuators controlledthereby and the sensors connected therewith forms a control arrangementfor controlling the transfer of the harvested crop from the harvestingmachine 10 onto the loading container 18 of the transport vehicle 12.The latter is connected to a steering device 114, which controls thesteering angle of the rear, steerable wheels 24. Moreover, the controlunit 112 transmits speed signals to a speed setting device 116 which, byvarying the gear ratio, controls the speed of the transport vehicle 12.The control unit 112 is further connected to a throughput sensor 118which detects the distance between the pre-compacting rollers in theinlet channel, comprising a sensor for detecting the position of sensingframes 62 attached to a divider point of the harvesting attachment 28, apermanent memory 122 and comprising the actuators 46, 48 and 50.

In FIG. 4 a flow diagram is shown, according to which the control unit112 of the harvesting machine 10 operates during the harvestingoperation.

After the start in step 200, step 202 follows, in which the control unit112 causes the computing device 88 to request the contents of the memory120 from the computing device 102. Data is contained therein, forexample regarding the engine output of the transport vehicle 12, itstype (in this case: tractive machine and/or tractor) and the tires(width, diameter, profile size). Moreover, by means of the input from anoperator into an input device the computing device 102 obtains dataregarding the dimensions of the loading container and the load bearingcapacity of the trailer 16. This data could also be contained in thememory 120, or such data are stored in the memory 122 for differenttrailers 16, and may be selected by the driver of the harvesting machine10 or by means of a barcode reader 124 which detects suitable markingson the trailer 16 or on the outer wall of the loading container 18. Thebarcode reader 124 could also be replaced by an RFID chip or transponderchip reader (not shown), which may read RFID chips or transponder chipsattached to the trailer 16 or to the loading container 18. These chipscontain the aforementioned data regarding the dimensions of the loadingcontainer 18 and the load bearing capacity of the trailer 16 or (similarto the barcode) only identification data, from which the aforementioneddata may be read from the memory 122. Moreover, the control unit 112also obtains data regarding the ground conditions. In this connection itis the lateral inclination and the inclination of the ground in theforward direction and data regarding the traction properties of theground (for example whether it is loose sandy ground or relatively solidground or damp ground). This data regarding the ground conditions isread from a card stored in the memory 122 using a path planned for thenext harvesting process, stored in the memory 122.

In the following step 204, the loading strategy is determined, usingwhich the loading container 128 is to be filled. The loading strategydefines the positions and the associated time periods in which thedischarging device 40 will unload the harvested crop. Thus thehorizontal and vertical dimensions of the loading container 18 and itsload bearing capacity are taken into account, the density of theharvested crop being able to be derived from empirical values or beingable to be measured by suitable sensors. Moreover, the type of transportvehicle 12 is taken into account. In the case shown here, the loading ofthe loading container 18 is initially carried out in its front region,in order to ensure a sufficient loading of the rear driven wheels 66 ofthe transport vehicle 12 via the towbar 14. A truck with a driven rearaxle and loading container (not shown) arranged thereabove would,however, initially be filled in the rear region. The engine output ofthe transport vehicle 12, the data regarding the tires and the tractionproperties of the ground influence the intended filling level of theharvested crop in the loading container 18, in order to avoid the wheels66 sinking into the ground or spinning in unfavorable conditions. Theinclination of the ground also influences the loading strategy, in orderto fill the side of the loading container 18 located uphill in each caseto a higher level than the side located downhill. The data required instep 204 was supplied in step 202 to the control unit 112. The loadingstrategy may provide that the loading container is filled according todefined patterns, which are covered once or repeatedly. Examples of suchpatterns are strips extending in the forward direction along the middleof the loading container or zig-zag patterns extending from front toback. However, any other patterns are conceivable. In a possibleembodiment of the present invention, two different basic loadingstrategies are stored, of which one starts with the loading of theloading container 18 at the front and the other at the back, and whichare selected using the type of transport vehicle and/or the position ofits driven wheels. The other aforementioned data thus serves to adaptthe selected loading strategy to the respective operating conditions.

After the loading strategy in step 204 has been determined and stored inthe memory 122, step 206 follows in which the harvesting machine 10 issteered along the edge of the harvested crop 54, by the control unit 112providing steering signals to the steering device 114, which are basedon the signals from the position determining device 72 and a card storedin the memory 122, which defines a path planned for the next harvestingprocess, or based on signals from the sensing frames 62 or a combinationof both signals. Alternatively or additionally, the edge of theharvested crop 54 is detected by a two-dimensional or three-dimensionalcamera and an image processing system or a laser or ultrasound sensor orscanner and used for producing the steering signal for the steeringdevice 114. The path of the harvesting machine 10 does not necessarilyhave to run dead straight, but may also include curves depending on theshape of the field. Moreover, turning procedures at the end of the fieldare provided.

The speed of advance of the harvesting machine 10 may be predeterminedby its driver, or the control unit 112 uses the throughput signals ofthe throughput sensor 118 in order to control the speed setting device116 so that a desired throughput is achieved through the harvestingmachine 10.

Moreover, in step 208, the transport vehicle 12 is guided parallel tothe harvesting machine 10, by the control unit 112 transmitting to thecomputing device 102, via the computing device 88 and the radio antennae74, 78, data regarding the position to be controlled by the transportvehicle 10. The computing device 102 then controls the steering device108 and the speed setting device 110 accordingly, by comparing theposition detected by the position determining device 76 with theposition to be controlled and, depending on the result of thecomparison, emits suitable steering signals to the steering device 108.This comparison and the generation of the steering signal for thesteering device 108 could also be carried out by the computing device 88and/or the control unit 112 on-board the harvesting machine 10, thepositional data being transmitted from the position determining device76 of the transport vehicle via the radio antennae 74, 78 to theharvesting machine 10, whilst the steering signals are transmitted backin the reverse direction to the transport vehicle 12. The transportvehicle 12 follows the harvesting machine 10 even when driving aroundcurves and when turning at the end of the field.

In step 210 the actuators 46, 48 and 52 are activated for adjusting theposition of the discharge end of the discharging device 40 and thedirection of ejection according to the loading strategy planned in step204, so that the loading container 18 is gradually filled in the plannedmanner. Additionally or alternatively, the position of the transportvehicle 12 varies in the forward direction and/or in the lateraldirection relative to the harvesting machine 10, by the control unit 112transmitting to the computing device 102, via the computing device 88and the radio antennae 74, 78, corresponding data regarding the positionto be controlled by the transport vehicle 10. As a result, the path ofthe harvested crop between the discharge end of the discharging device40 and the loading container 18 may be kept relatively short, which hasthe advantages that in windy conditions little harvested crop is lostand the harvested crop is pre-compressed on the loading container 18.

Step 212 then follows, in which it is queried whether the loadingstrategy has been completely carried out. If this is not the case, step206 follows again. Otherwise, step 214 follows. As the loading strategyhas been fulfilled, in this step an information device (not shown)operated optically or acoustically by the control unit 112 via thecomputing devices 88, 102, causes the driver of the transport vehicle 12to undertake control of the transport vehicle 12 and to clear space inthe vicinity of the harvesting machine 10, in order to create space fora transport vehicle which follows. Alternatively, the steering unit 108of the transport vehicle 12 is activated to move the transport vehicleforward to the side, whereupon the driver of the transport vehicle 12takes control. The transport vehicle 12 which follows is positioned byits driver alongside the harvesting machine 10 and step 202 againfollows. If this step 202 has to be repeated for the same transportvehicle 12, the control unit 112 may also refer back to the alreadypreviously stored loading strategy.

It should be noted that in a simplified embodiment of the invention thedriver of the harvesting machine 10 steers said machine andpredetermines its speed, whilst the driver of the transport vehicle 12steers said vehicle and predetermines its speed. The control unit 112then only controls the actuators 46, 48 and 52 according to a loadingstrategy selected manually by the driver of the harvesting machine fromat least two available loading strategies, and which preferably dependson the position of the driven wheels of the transport vehicle 12, asmentioned above. These loading strategies may be modified by the driverof the harvesting machine 10 manually according to the size of theloading container 18, for example by the discharging device 40 beinginitially positioned on the front and rear wall of the loading container18.
